NZ Chapter Event: Working Stress- the New Zealand rail bridge rating story
August 16 @ 10:30 am - 11:30 am AEST
Join the RTSA New Zealand Chapter and Mike Keenan (KiwiRail) to hear about the history of how rail bridges in New Zealand are “rated”. This presentation is being held as an RTSA New Zealand online meeting.
KiwiRail maintains a substantial rail infrastructure network of which its bridge stock are an essential component. These bridges have been developed over the 160 year life time of New Zealand’s railway and are a key enabler of the networks overall capacity. How these bridges are “rated” to determine their load carrying ability has likewise developed over time. This presentation will describe the background to choices made, the influence of other overseas railways, how the rating is now done and some of the challenges that the network faces.
Mike Keenan is part of the team responsible for engineering oversight of KiwiRail’s structures assets. He has been working on inspection, maintenance and renewal of the rail network in New Zealand for the past 15 years.
